Nintendo won [PDF] the case in 2012, but (as always) had to wait until February 2013 to have the case upheld on appeal.

In June 2013, the US federal circuit upheld that decision, which included the award of US$236,000 in fees to Nintendo – which has branded IA Labs a "defunct patent troll."

Nintendo has now claimed that the payments didn't happen – and as a result, “a sheriff's sale Montgomery County, Maryland, was conducted to sell IA Labs' remaining assets, including its patent portfolio. Nintendo obtained IA Labs' entire patent portfolio at that sale as partial repayment for litigation costs.” ®
